The simplest system that is sufficient for chest drainage is a one-chamber system. It uses either a Heber-drain or an active suction source and comprises a single collection canister. For active or passive air evacuation, a water seal component is attached. To ensure that all air is sucked out when using a Heber-drain, manual support might be ...

[1] Without a vent, negative pressure can slow the flow of water leaving the system, resulting in clogs, or cause siphonage to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.
